Here.

Of course, given the 4 billion year timeline, I’m not buying insurance just yet.

I guess there could be prevailing intergalactic winds as a result of a collision. Add gravity trying to recapture the outflows giving the curved appearance. Oh yeah, just guessing here too.

I'd need to find out more about the proper motion of the galaxy, but I remember an article about us colliding with Andromeda someday, which implies that our galaxy is moving sort of "away" from our view of the center, not side-to-side. Just guessing here. “Wind shear?”

Very cool. But I'm guessing that there was a lot of processing to merge the optical and radio images. I’ve seen a lot of pictures of the Milky Way but none like that. Very cool.
